Visopsys version 0.69 was released today. Four months in the making, this is a maintenance release comprising the final round of tweaks and bug fixes to the 0.6x series of Visopsys, featuring lots of work on the USB subsystem including support for USB mice/keyboards and hubs, tuning of the FAT filesystem driver, usability fixes for various user programs, and loads of OS kernel and C library improvements and bug fixes. As always you can demo Visopsys as a live CD or run a scaled-down version from a floppy disk. Change log is here, and downloads are here.
